ENVISAT MERIS Regional Mapped Cyanobacteria Index (CI) Data, version 6.0
Listed in NASA Earthdata CMR
CyAN CI delivers the Cyanobacteria Index for contiguous U.S. (CONUS) and Alaska.
Description
The standard product is CI_cyano, which is filtered for cyanobacteria dominated waters only. Products are designed for fast ingest by water-quality managers and researchers monitoring freshwater HABs.
The algorithm and processing details are documented in the official release notes. Geophysical variables in this suite include: - band1 – Cyanobacteria Index (DN-encoded) (digital number, unitless)
